The development of virtual reality (VR) technology has spawned new concepts of patient interaction and behavioral modification. The extension of techniques developed for virtual surgery training and pilot training provides the basis for retraining patients with neurological deficits resulting from multiple sclerosis, spinal cord injury, and stroke. Moreover, the application of VR can be of substantial benefit in compensating for sensory deficits, particularly in vision and hearing.

VR approaches can be directed toward assisting the performance of motor and sensory tasks; VR also can be used to develop novel modalities of physical therapy to improve unassisted performance. New modalities of diagnosis and treatment of sensorimotor processing deficits and cognitive dysfunction are emerging from the confluence of clinical neurology, basic science advances, and computer science. In this article, the design considerations of these assistive, diagnostic, and therapeutic systems are reviewed.
